The fluorescent dye dilution method for determining the liquid-water content in snow is based on measuring the concentration change of a solution when it is mixed with snow. Samples for analysis can be obtained rapidly and reliably, and, unlike calorimetric or equilibrium-temperature methods, field use requires no on-site data analysis.
La méthode des dilutions à variation de couleur de fluorescence pour la détermination de la teneur en eau liquide dans la neige est basée sur la mesure de la variation de la concentration lors de son mélange avec la neige. Des échantillons pour l’analyse peuvent être obtenus rapidement et de façon fiable, et, contrairement aux méthodes calorimétriques ou d’équilibre de température, les prélèvements ne nécessitent pas d’analyses in situ.
Die Methode der fluoreszierenden Farblösung zur Bestimmung des Wassergehaltes im Schnee beruht auf der Messung der Konzentrations-änderung einer mit Schnee vermischten Lösung. Proben für eine Analyse können schnell und zuverlässig gewonnen werden; im Gegensatz zu kalorimetrischen oder Temperaturgleichgewichts-Methoden erfordert der Gebrauch im Feld keine Analyse am Beobachtungsort.
